Customs question

Ok so i've imported items from china before and one time US customs seized one of my shipments because it was unauthentic items. Now im paranoid about all this happening again. I have another shipment coming in to another address and today when i looked up the tracking # this is what it said:

REGISTERED WITH CLEARING AGENCY;SHIPMENT SUBMITTED TO CLEARING AGENCY

That doesn't mean that it got seized by customs does it? What does it mean?

I don't think it is seized but possibly held for duty taxes. You are best to contact the shipping company via email and ask them as they should be able to help you :)

anyone else on here know?
